FIELD: enrichment of minerals.;SUBSTANCE: present invention relates to mineral processing and can be used for carrying out of flotation experiments at investigation of different ores for enrichment in laboratories of concentrating factories or scientific research or training institutes. Laboratory flotation machine comprises a chamber, an impeller unit comprising a bearing housing, a shaft, a above-impeller cap, an impeller and a magnetic mixer. Chamber is installed on a magnetic mixer, the rotating magnetic field of which drives the impeller into rotation. Impeller is made of magnetic material, and the chamber, the above-impeller cap and shaft are made from nonmagnetic material.;EFFECT: reduction of metal consumption and labor input for production of flotation machine.;1 cl, 1 dwg
